New DeSignz Impulse R.I.P. High Flow Angled Port Valve


From the Web site:

Looking to blow your competition away? Well our new valve will set you apart and on your merry way. Made from aluminum and Delrin, this is a lightweight but also a highly reliable choice.

  • Radial intake port profile R.I.P.
  • Angled exhaust port for maximum air flow
  • Internal spring for no disruption of air flow or lost springs
  • Initial tests show and increase of 20+fps from a stock valve and 40+fps on an LPR setup Imp. 140psi inlet, 60psi bolt pressure.
  • Many more shots per tank, not 10 or 20. How about hundreds...
  • Our valve weighs only 17.6 grams, w/O-rings, lightweight by comparison
  • Our Delrin valve has a small surface area which makes it easier to open under pressure
  • Comes complete as shown w/ O-rings

Comments

Before installing my New DeSignz High Flow Valve I removed the stock valve and really tried to compare the two.  I wanted to try and see if I could see what made this valve better than the stock valve.

The Stock Impulse valve has a very simple design.  It consists of a Delrin sleeve called the Valve Seat (some call it the Valve Body) and the actual Valve.  Although both parts are delrin, which is self lubricating, there is an o-ring on the back of the valve to help seal the valve when closed.  This o-ring requires dow 33, so it needs maintenance.  How it works is equally simple.  When the hammer comes forward and hits the valve and moves it forward.  Once moved forward it allows air flowing in from the valve cap to go up into the bolt and propel the ball.  The spring really only serves a single purpose and that is to keep the Valve aligned correctly and closed when your Impulse is not in use.  Many people remove this spring because it has a bad habit of making a springy or "boinging" sound when you fire your Impulse. 

The New DeSignz High Flow Valve is a little more complex, but at the same time very simple to install and utilize.  While the stock valve is made up of three parts, not counting o-rings, the High Flow Valve is an all in one unit.  It has an integrated valve and spring.  This means that there are no serviceable parts so it is maintenance free.  One thing I noticed is that the New DeSignz Valve is angled or ramped on the inside.  While I am not a air flow expert, I do know that many of the high perforce bolts are angled where the air flows into the bolt.  To me it's only logical that whenever you are trying to change the direction that air flows, an angle is better than a 90* turn.  The stock valve is not angled.

Installation Instructions:

Installation is easy but will take some time.  Don't let the number of steps scare you.  I tried to be as detailed as possible.  Remember both technical and not so technical people read the Impulse FAQ (but all are Smart!!)

  1. Degas the marker.
  2. Remove the bolt pin and slide the bolt out the back of the marker.
  3. Remove the valve cap.
  4. Once the Valve cap has been removed, remove the valve spring and valve.
  5. Unscrew the hammer assembly from the back of the marker
  6. Remove the two screws that hold the grip frame and solenoid tray to the body.
  7. Separate the grip frame from the body.  If you have a non-Vision Impulse be careful when removing the grip frame and solenoid tray and remember to disconnect the board from the solenoid.
  8. If you have a Vision Impulse, you will need to remove the ball detent on the eye side of the marker as well as the eye cover.  You will also need to disconnect the Vision eye board from the solenoid and then remove the two screws holding the Vision eye board in place. 
  9. On the underside of the body is the screw that holds the valve Seat (Valve Body) in place.  Remove this screw.
  10. Push the stock Valve Body out the BACK of the Impusle.  It will not fit out the front.
  11. Slide the included o-rings onto the High Flow Valve.  Lube them with some Dow 33.
  12. Insert the rounded side first into the back of the Impulse.  When installed correctly the hammer will come forward and hit the little dimple shown on the left side of the picture above.  Make sure that the ramped hole is facing up and the solid hole is on the bottom.
  13. Push the High Flow Valve up into the Impulse until it lines up with the hole in the bottom of the Impulse body.
  14. Screw in the valve screw so that it is flush with the body.
  15. Put the Valve Cap back on.  Do not put the stock Valve Spring back in.
  16. Since it is out, clean and lube the hammer assembly.  Then screw that back in place.
  17. If you have Vision, install the Vision eye board, eye cover and eye side ball detent.
  18. If you have a non-Vision Impulse, connect the solenoid to the board.
  19. Attach the solenoid tray and trigger frame to the body.
  20. Put the bolt back.  Make sure it's not upside down and make sure that the bolt pin catches the hammer.
  21. Last step, load it up and enjoy!!!

The Test

For this test a stock Adrenalin Impulse was used.  The setup consisted of the following:

  • The entire gun was cleaned and lubed, prior to the test.
  • Although fairly new, the Adrenalin Impulse has seen several cases of paint so the reg and all parts are broken in.
  • The Dwell was not adjusted once the test started.  To verify that the Dwell remained the same, I first set it to it's lowest setting.  I then counted the number of chirps before testing the stock setup.  After I replaced the valve, I then repeated the process and set the Dwell back to where it was before.
  • The output pressure on the max-flow was set at 175psi.
  • For the test the air source was a Smart Parts Low Pressure Max-Flow compressed air tank running on gun.
  • The paint used in the test was a generic "practice paint".  This paint was not consistent in size and in the test results the variance shows.
  • The barrel was a 14" Freak with a .684 insert.
  • Before each first shot was recorded two clearing shots were taken.
  • Paint was fed into the marker by an Evolution II.
  • From a previous test, the installed bolt was a VooDoo delrin bolt.
  • The same Chronograph was used to record the velocity of all shots.

Change

29.75 -0.16 33 35 2 29.28

As you can clearly see by changing nothing other than the valve I recorded an increase in velocity of 29.75fps.  ALMOST 30FPS!!!!  This valve is WAY more efficient than the stock valve.  While not everyone will see the exact same performance increase, I would expect that everyone will see some increase.

Once again New DeSignz has created an Impulse product that is innovative beyond words and performs better than expected when put to the tests in "wolverine's lab".  I have said this before and I will say it again, if it says New DeSignz on the box, buy it cause it's the best!

The Details

  • Installation: Installation is easy.  Will require you to disassemble most of your Impulse.
  • MSRP: $34.95.
  • Options: None.
  • Pro's:  This valve will drastically increase the performance of your Impulse and you will no longer need the stock valve spring, so that boinging springy noise will go away too  It's also maintenance free!!
